while you remain motionless, you are indistinguishable from a normal tree.

You have two creature types: humanoid and plant. You can be affected by a game effect if it works on either of your creature types.

Because of your unusual shape, you cannot wear armor of any type. However, your Armor Class equals 13 + your Constitution bonus. You still gain the normal benefit of using shields as long as you are proficient with them.

Your Strength score increases by 2, your Constitution score increases by 1, and your Dexterity score is reduced by 2.

You take double damage from fire and fire spells and effects.

You can speak, read, and write Common and Sylvan.

• Spring. You are in a delightful mood and positively bursting with energy. During the spring, your walking speed increases by 10 feet and you have a +3 bonus to your initiative checks.
• Summer. You are temperamental and quick to action. During the summer, when you hit with a melee weapon attack you deal 2 extra damage.
• Autumn. You are solemn yet eager to help your allies. During the autumn, when a creature that you can see targets an ally within 5 feet of you with an attack, you can use your reaction to swap places with your ally, and you become the target instead.
• Winter. Your mood is dark as you frequently reflect on life and death. During the winter, you have resistance to necrotic damage. In addition, you make all death saving throws with advantage.
• Variant: Evergreen. If you like, you can choose to be an evergreen treant and your mood stays the same throughout the years. As an evergreen tree, your allies can use your dense needles to avoid attacks. Any ally within 5 feet of you has the benefits of half cover as long as you are within 5 feet of the attacker and are aware of it.
